[PATCH] block-sha1: Use mozilla-sha1 copyright and license information

[Ulrik Sverdrup <ulrik.sverdrup@gmail.com>]

block-sha1 needs an independent copyright and license header, in the
case that the original mozilla SHA-1 implementation is removed from
the tree.

The Contributor(s) list in the header is not in the git style, but
it is copied as well, and augmented with git contributors to
block-sha1.

block-sha1/sha1.{ch} simply say this:

/*
 * Based on the Mozilla SHA1 (see mozilla-sha1/sha1.c),
 * optimized to do word accesses rather than byte accesses,
 * and to avoid unnecessary copies into the context array.
 */

This means that if mozilla-sha1 is removed, we need to copy the
license information back to block-sha1.
